A 77-year-old woman presented for treatment of wounds she suffered when she fell to the sidewalk 2 days earlier while chasing after her dog.
Key point: These types of wounds are common among the elderly, even following relatively minor trauma. She presents with a combination of ecchymoses and erosion due to a combination of blunt force and sheering force exerted on fragile skin.
Treatment: Inquire about pain or limited range of motion, which might suggest a minor fracture. The ecchymoses can be treated by intermittent application of cold (crushed ice in a plastic sandwich bag for 5 to 10 minutes an hour). However, this is most effective during the immediate post-traumatic period. The eroded areas should be covered with an antibiotic ointment to prevent infection and to promote a moist healing environment. The area should not be covered with a bandage, because the adhesive will lead to further skin tearing on removal.
Note: Keep interventions simple and practical. Given time, this would will heal very nicely without complex, time-consuming measures.
